Having thus described my invention, I claim: 
     
         1 . A cap for a smoke pipe, said smoke pipe having a burn tube for containing and burning a substance and a holder for the burn tube, said cap comprising:
 a proximal end having an internal circumference that sealably fits over the holder of the burn tube; and   an elongated internal aperture that accommodates a length of a burn tube; and   a distal end that can be gripped by users for attaching or removing said cap from the burn tube.   
     
     
         2 . A smoke pipe system comprising:
 a smoke pipe having a mouthpiece on a proximal end and a burn tube holding aperture on a distal end with a inhalation conduit aperture extending from the proximal end to the distal end;   a burn tube for containing and burning a substance inserted into the aperture on the distal end of the smoke pipe; and   a cap with a proximal end having an internal circumference that sealably fits over the holder of the burn tube and an elongated internal aperture which accommodates a length of a burn tube and a distal end that can be gripped by users for attaching or removing said cap from the burn tube.
